Power button and boot problems - Galaxy S 4 Q&A, Help & Troubleshooting

Hello friends. I have a problem with my Samsung i9500 Galaxy S4. The thing is I can not use the button of power on or turn to lock the screen because the phone is turned off or rebooted and the Samsung logo appears, then it looks like is about to initialize but then reappears Samsung logo. The only way I can turn on the phone is by pressing the buttons of recovery mode and after about 3 attempts, the phone starts normally. I have the stock Rom 4.3 Jelly Bean. On the other hand this started since I took out the SD memory. I have reinstalled the ROM again and continued doing the same. No it may be. I think it is a problem in the boot but I can not solve it. I can not lock the screen with the power button because the phone turns off. I hope you can help me. regards

[Q] Unusual bootloop

Hi all, i installed the CM11 on my gf's Galaxy s3 (i9300 international version), the problem is that sometimes it randomly reboots and get stuck in an unusual bootloop. It reaches the bootsplash logo and it keeps rebooting, the only solution to get it back to work is to remove the battery for at least 30 seconds and try to turn it on, sometimes it works.
When the bootloop happens i'm not able to enter the recovery mode, because it just turns on and it keeps rebooting, same thing with download mode.
So, i'm new here, but i read about a common issue which is the sudden death syndrome and half-sds, it might be that? I checked and it has the insane chip.
Any advice/idea? It would be better to flash a stock ROM to be safe?
I would backup the whole device, recover initial firmware using kies emergency recovery mode and then start over again.
Had a similar problem but even worse: same bootloop, but no dice on recovery :\
Was unable to reflash or restore old firmware using Odin, Kies was the only thing that worked for me.

Do the reboots occure few seconds after pressing the power button?
I have exactly the same problem and I figured out that my power button is kinda stuck and thus permanently pressed.
This causes the permanent reboot, because holding the power button for a certain amount of time causes a reboot.
Try to push "Vol down"+"Homebutton" instantly after a reboot. If your galaxy enters the download mode (before rebooting again), you have the proof, that it's the fault of the power button due to the fact that pressing the power button would have been necessary.
I hope the fix will be for free under warranty.
At the first moment I also thought it would be the Sudden Death syndrom, but thankfully it's not the case and only the power button has to be fixed.

I don't know, i didn't paid attention to it. Anyway thanks to both of you for the replies, i'll check the power button as soon as possible since i don't have the phone with me right now. If that's not the cause, i think i'll do an emergency recover with kies as suggested by Cy4n1d3.
Now i still have a doubt, CM11 should have the fix for the sudden death syndrome merged into its code right? I'm asking this because if i'm right i could exclude sds as the cause of the problem...
Rebooting is not an SDS symptom, SDS is totally dead -suddenly.
Power button failure is diagnosed by inserting the battery, if it turns on by itself then button contacts are shorted out.
Your problem sounds more like corruption of the cache or dalvik, wipe and reflash your rom or go back to stock to test. Check MD5 of downloads and don't restore anything before you test.

Have you tried restoring your device to it's original factory settings?
As much as I didn't want to, yes. It's still giving me the same problem.
Try flashing stock rom with odin.

S4 - Screen going black after boot (Samsung Galaxy 4 logo) Not booting - no recovery*

Hi Everyone,
I bought a S4 online and hoping to get it fixed. Here's the problem:
When I turn the phone ON, the phone boots up and vibrates and Samsung S4 logo appears.
As soon as the logo appears, the phone suddenly turns off and the screen goes black.
I cannot to go recovery mode.
Could this be a hardware or software issue?
Any guidance will be helpful.
Thanks in advance.
It could be both. It could even be a battery problem.
Try flashing the firmware again using Odin. If you can boot the phone in download mode. If flashing firmware doesn't do it, then it might be hardware related.
Exactly this happened to me. I was using my phone and it suddenly died, every time I tried to turn it back on it would get to the Galaxy S5 splash screen and turn off again. It did the same trying to get to recovery. If I tried download mode it would flash up quickly then turn off.
Turns out my power button was faulty.
My fix......I took my phone and pressed power button over and over again for about 1 minute as fast as I could
It's worked perfectly ever since.
Worth a try, what have you got to lose!?

this morning a friend of mine gave me his s3 neo with the same problem, bootloop, and no recovery, and no download mode, I put my battery, and I pressed for 10 minutes, continuously the power button, and in the end it was switched on normally, I went into recovery, wipe and I installed the firmware, after a custom rom, and the phone is fine, but if I put back the battery of my friend, restart the bootloop, it is the battery not the power button!
